A Test of Learning and Memory

To measure cognition in rats, ARS scientists
used video imaging of a pool to track the route rats to find a submerged
platform (the end point of their swim). These diagrams show the top views of
the routes taken. In the trials, the rats fed the standard chow took longer to
find the platform and showed little or no progress in learning. In the same
water maze, rats fed the blueberry extract learned to locate the platform
faster.Click the images for more information and to download high resolution
